Bump github.com/cloudposse/atmos from 1.189.0 to 1.196.0

[dependabot]

Bumps github.com/cloudposse/atmos from 1.189.0 to 1.196.0.

Release notes

Sourced from github.com/cloudposse/atmos's releases.

v1.196.0

what

• Add Google Cloud Storage (GCS) backend support to !terraform.state Atmos YAML function
• Implement performance optimizations (client caching, retry logic, extended timeouts)
• Create unified Google Cloud authentication system for consistency across GCP services
• Update documentation with GCS backend usage examples and authentication methods

why

The !terraform.state YAML function allows reading the outputs (remote state) of components in Atmos stack manifests directly from the configured Terraform/OpenTofu backends.

Previously, the !terraform.state YAML function only supported:

• local (Terraform and OpenTofu)
• s3 (Terraform and OpenTofu)

This PR adds support for:

• gcs (Google Cloud Storage - Terraform and OpenTofu)

With GCS backend support, users can now leverage the high-performance !terraform.state function instead of the slower !terraform.output or !store functions when using Google Cloud Storage for Terraform state storage.

Implementation Details

GCS Backend Features

• Full Authentication Support: JSON credentials, service account file paths, and Google Application Default Credentials (ADC)
• Service Account Impersonation: Support for impersonate_service_account configuration
• Performance Optimizations:
  • Client caching to avoid recreating GCS clients for repeated operations
  • Retry logic with exponential backoff (up to 3 attempts) for transient failures
  • Extended timeouts (30 seconds) to match S3 backend performance
• Robust Error Handling: Graceful handling of missing state files and detailed error context
• Resource Management: Proper cleanup and explicit resource management

Usage

The GCS backend works seamlessly with existing !terraform.state syntax:

# Get the `output` of the `component` in the current stack
subnet_id: !terraform.state vpc private_subnet_id
Get the output of the component in the provided stack
vpc_id: !terraform.state vpc dev-us-east-1 vpc_id
Get complex outputs using YQ expressions
first_subnet: !terraform.state vpc .private_subnet_ids[0]
</tr></table>
